PIPE CLEANER.

7 Application filed. October 31 1925. Serial No. 65,928.

The present invention relates to a pipe oleaner and aims to provide a simple, practicable and etfioient device for removing the incrustations or deposits formed within the bowls of smokers pipes, and one which will be equally well adapted for cleaning pipe bowls of various shapes and sizes.

According to my present invention I provide a device of the character described 10 which consists'of a. self-centering frame of preferably conical form adapted toengage 'o ver the outerwall of a pipe bowl when pressed over the mouth thereof, the top of the frame being formed with a central openmg in which is mounted a carrier for a cutter adapted to be moved both longitudi nal-ly and rotatably with respect to the frame, and means on said frame for holding it against movement during the act of cleaning out or removing the incrustation from the: interior of the pipe bowl. The invention alsoresides in other: specific details of im-, provement which wi ll be hereinafter more "fully described.

bodiments of myv invention wherein Figure lis a perspective view of the device with a part thereof broken away to disclose the cutter.

Fig. 2 is a longitudinal section of a pipe having the device of Fig. 1 applied thereto. Fig, 3 is a transverse section of a pipe showing a modification of the device shown in Fig. 1 applied thereto.

l igs. 6 and 7 are details of a modified 40 form'of cutter device used with my inven tion. p r

Referring to the drawings let A indicate a smokers pipe of any conventional form having a tobacco receiving bow-l B, the in teriorof whichis shown coated with an inorustation or deposit C. This deposit, it wi ll be understood, if not removed, will continue to grow, thereby reducing the ,capacity of the pipe'bow'l and also tend to close up or seal the passage av through the pipe stem. move this deposit from time to time, and according to the present invention I have provided an improved pipe cleaner for accomp-dishing this result;v

The accompanying drawing shows two ema It is therefore advisable to re;-*

In Figs. 1 and 20f the drawings my pipe cleaner is shown as consisting of a frame D which is preferably of internal conical form S0 as to adapt it to over pipe howls of different iamet r The coni l tor-m the rame also s to renter h f ame with respect tothe bowl when applied there over. The frame at its top is formed with a a E ha ng a c nt al op ning her .in in which is mounted a cutter carrier. G

The frame D, it will be understood, may be fo m d re metal, fib e r oth su able substant ally rigid material, and in order that the cutter carrier G may he suiti ably supported'anda more sturdy construction result I prefer to form the top ofthe frame E w th bu hingextensi E, whi it will be obvious, will also be internally tl'lreaded-as is the top E, The interior wall of the frame 1) may also be lined with a thin piece ofleather or other soft material d t P event ma r s 0f the Pit h w The cntter ,carrier G is proyided at its innerend with a critter herein shown as.

P ef r t h he set e H m mora y m nt d o the vcar ie if, a proride a number of emitters of different sizes whereby pipe Joowls ,of various internal diameters-may be reamed out to their proper size. The cutter is accordingly formed with a. central threaded opening 7; adapted to engage over-a reduced threaded end yon the carrier (i, and the cutter held in place thereon by a screw K entering the end of the reduced shank and engagipg {the bottom face of the cutter. An alternative met-hod of securing the cutter to the carrier shown in Figs. 6 and 7 wherein the cutter H is formed with a central square opening Z0 adapted to over a reducedsqnare shank formed on the inner end ,o-fthe carrier 6;, theeutter being held thereon by a screw K in the same mannerqas shown l .3.

In order that the pipe cleaner may be suitably held upon the pipe bowl during the cleaning operation the frame D is provided with apair of oppositely disposed hook-like members L adapted to be grasped by the fingers of the operator while holding the bottom of the bowl of the pipe in the palm of his hand.

. In Figs. 3 and 4 I have shown an alternative construction fonaccomplishing the same result, wherein the hook-like members L pivotally support a U-shaped member or bail M which is adapted to assume a position embracing the lower portion of the bowl and which is provided at its central portion with ,an adjustable clamping member N adapted to engage the bottom of the bowl. to draw the frame downwardly overthe top of the bowl. As herein shown, said clamping member N consists of a screw-threaded shank a threaded through a bushing enlargement m, formed onthe U-shaped member, the inner end of the threaded shank 1 having a clamping plate a swiveled thereto and the outer end of said shank having a manipulating knob at? If desired, the engaging face of the clamping plate n may be covered with a piece of felt n 'or other soft material to prevent scratching'or marring of the polish on the pipe bowl.

In use the frame D is applied over the mouth of the pipe bowl which is then taken in the palm of the hand, two' fingers of which are then caused to straddle the hook-:

the pipe bowl. In the modification shown in Figs. 3 and 4, instead of the operator straddling the members L with his fingers, the U-shaped member is brought down into position below the pipe bowl and the knob a is turned to movethe clamp a into engagement with the bottom ofthe bowl to draw the frame downwardly over the top thereof. After the cutting away operation is completed, the clamp a must be released from its engagement through turning of the'knob 11 111 the opposite direction, after which the Ushaped member M is raised about its pivotal connection to clear the pipe bowl and the device as a whole is remove therefrom. i

From the foregoing description it will be appreciated that I have providedan 'exceedingly simple, practicable and efiicient pipe cleaner adapted for use on smokers pipes of different shapes and sizes, the only occasional adjustment being the change from one size of cutter to another where the interior diameters of the bowls to be cleaned I are very different.

\Vhile I have shown and described two specific embodiments of my invention I desire it to be understood that various changes in mechanical construction and shapes of parts employed may be resorted to without departing from the spirit of my invention, as embraced in'theappended claims.

lVhat I claim is: V I
